Piezoelectric Amplifier Circuit: Piezo buzzers can be found everywhere, next time you throw out an old smoke detector be sure to remove the piezoelectric element from it and stash it in your parts bin. If you want to monitor sound with a piezoelectric element it’s not that easy since the voltage produced by the device is so small.
Piezoelectric Heat Sensor: Here is an Ultra sensitive Heat Sensor to monitor high temperature in Electronic devices. It can be placed inside the electronic gadget that usually generates heat during its operation. The circuit also functions as a sensitive Fire Alarm. This heat sensor uses the piezoelectric property to sense heat.
